Abnormal noises when a car just starts moving can be attributed to the following reasons: 1. The car has not been used for a long time: The engine oil returns to the oil pan, meaning the top of the engine, specifically the valve chamber, lacks sufficient oil. Since the valves are missing the sealing and lubrication provided by the oil, abnormal noises can be heard from the bottom of the car when it is first started. This situation is considered normal. 2. Issues with the engine belt: Abnormal noises from the engine belt occur because the belt is dirty. Cleaning it with water or applying some lubricant can eliminate the noise. However, whether this solution is suitable for all car models requires further analysis.

What is the purpose of rotating car tires?

The purpose of rotating car tires is: 1. To achieve more even tire wear; 2. To extend the service life of tires; 3. To prevent abnormal tire wear; 4. To improve driving safety. The functions of tires are: 1. To directly contact the road surface and work with the car suspension to cushion the impact during driving; 2. To ensure good ride comfort and smooth driving; 3. To maintain good adhesion between the wheels and the road surface, improving traction, braking, and off-road capability; 4. To bear the weight of the car. Methods for tire maintenance include: 1. Avoiding curbs and potholes to prevent sidewall ply breakage and tire bulges; 2. Regularly removing debris from tire treads to avoid blowouts; 3. Checking tire wear and replacing them in time; 4. Performing four-wheel rotation to prevent excessive wear; 5. Regularly checking tire pressure to ensure it is neither too high nor too low.

What is the correct way for a car to pass over a speed bump?

The correct way for a car to pass over a speed bump is to reduce speed before crossing, then slowly pass over it with both wheels perpendicular to the bump. This method allows both left and right wheels to contract simultaneously, with the ground force being evenly distributed between the springs and shock absorbers of both wheels. Even force distribution helps minimize damage to the vehicle. Incorrect ways to drive over speed bumps include: 1. Passing with only one side's tires; 2. Driving over at high speed; 3. Crossing diagonally. Speed bumps, also known as speed humps, are traffic safety installations on roads designed to reduce the speed of motor vehicles and non-motorized vehicles.
